CVE-2014-3812
Official description Straight from the sourceThe vendor's or NVD's own wording, published unedited. Authoritative, but often terse — it says what broke, rarely what to do.
NVD · uneditedThe Juniper Junos Pulse Secure Access Service (SSL VPN) devices with IVE OS before 7.4r5 and 8.x before 8.0r1 and Junos Pulse Access Control Service (UAC) before 4.4r5 and 5.x before 5.0r1 enable cipher suites with weak encryption algorithms, which make it easier for remote attackers to obtain sensitive information by sniffing the network.
Technical summary Written by usOur analysis, written from the advisory, the CVSS vector and the affected-version data. It adds context the advisory leaves out, and never invents facts that are not in the source.
dbcve analysis · high confidenceJuniper Junos Pulse Secure Access Service (SSL VPN) and Junos Pulse Access Control Service (UAC) devices ship with weak encryption cipher suites enabled by default. These weak ciphers (likely including export-grade, 40-bit, or 56-bit encryption variants) allow remote attackers performing network sniffing to capture and decrypt sensitive VPN traffic.

Am I affected? How to checkSteps we derive from the advisory and the affected-version data, so you can decide whether this CVE reaches your setup. They are a guide, not a scan — your own configuration is the authority.
dbcve checksWork through these to decide whether this CVE applies to you.
-
Identify the installed Junos Pulse software versionAccess the device admin console or use the system information page to determine the exact version of Ive OS or Unified Access Control Software runningAffected if The installed version is Ive OS 7.4, Ive OS 8.0, Unified Access Control Software 4.4, or Unified Access Control Software 5.0, or any version of the FIPS/Infranet controllers listed (6500, 4000, 4500, 6000 series)
-
Verify the SSL VPN service is activeConfirm that the Junos Pulse Secure Access Service (SSL VPN) or Junos Pulse Access Control Service (UAC) is enabled and accepting connectionsAffected if The SSL VPN or UAC service is running and accessible on the network
-
Check the enabled cipher suitesReview the SSL/TLS cipher configuration in the device admin interface under the VPN settings or SSL settings section, or retrieve the configuration via CLI command such as 'get ssl cipher' or equivalentAffected if Weak cipher suites including export-grade (EXP), 40-bit (EXPORT40, RC4_40), or 56-bit encryption variants are listed as enabled or allowed
-
Determine if weak ciphers are prioritizedExamine the cipher priority order in the SSL configuration to see if weak ciphers are positioned before stronger ciphers, or if no cipher restrictions are configuredAffected if No strong TLS cipher policy is enforced, or weak ciphers are explicitly allowed or preferred
A user is affected if they are running any of the listed vulnerable versions of Ive OS, Unified Access Control Software, or the FIPS/Infranet controller hardware, AND weak cipher suites (export-grade, 40-bit, or 56-bit) are enabled in the SSL VPN or UAC configuration.

Remediation Closing itWhat it takes to close this. Where a vendor fix exists we point at it; where none exists we say so plainly, and can build one. Effort estimates are scoped from the advisory, not from your codebase.
From vendor dataUpgrade to IVE OS 7.4r5/8.0r1 or later for SSL VPN, and 4.4r5/5.0r1 or later for UAC, or manually disable weak cipher suites in the device configuration and enforce strong TLS cipher policies.
